Ack-Ack: A 1st person shooter where the screen scrolls left or right, and up or down when you move a laser sight to destroy bombs fired from unseen aliens. Every time a bomb is fired, an indicator shows you which direction you should move to intercept it and each bomb must be destroyed before it reaches the ground or you lose one of three lives. You must destroy a certain amount within a life to move to the next level and an increase in the number of bombs. Two players can play and each player must wait for the other player to play a full game.
